Super Mario World is a 1990 platform video game developed and published by Nintendo as a pack-in launch title for the Super Nintendo Entertainment System (SNES) and is the fifth game in the Super Mario series. Development was handled by Nintendo Entertainment Analysis and Development, led by Shigeru Miyamoto, who directed the game along with Takashi Tezuka.
The game centers on the quest of Mario and Luigi to save Dinosaur Land from Bowser, the series' antagonist. The two brothers must travel across seven worlds to restore order to Dinosaur Land. It built on the gameplay of previous Mario games by introducing new power-ups that augment character abilities, and established conventions that were carried over to future games in the series. Super Mario World marks the first appearance of Yoshi, Mario's dinosaur sidekick and riding mount.
After saving the Mushroom Kingdom in Super Mario Bros. 3, brothers Mario and Luigi agree to take a vacation to a place called Dinosaur Land, where there are many types of dinosaurs. However, while resting on the beach, Princess Toadstool disappears. When Mario and Luigi wake up they try to find her and, after hours of searching, come across a giant egg in the forest. It suddenly hatches and out of it comes a young dinosaur named Yoshi, who then tells them that his dinosaur friends have also been imprisoned in eggs by evil Koopas. Mario and Luigi soon realize that it must be the evil King Koopa Bowser and his Koopalings.
Mario, Luigi and Yoshi set out to save Princess Toadstool and Yoshi's dinosaur friends, exploring Dinosaur Land for Bowser and his Koopalings. To aid him, Yoshi gives Mario a cape as they begin their journey. Mario and Luigi continue to follow Bowser, defeating the Koopalings in the process, and save all of Yoshi's dinosaur friends. They eventually make it to Bowser's castle, where they fight him in a final battle. They defeat Bowser and save the Princess, restoring peace to Dinosaur Land.
